Service Paper Element

Every 100 hours of operation (more often under

extremely dusty or dirty conditions) replace the paper

element.

1. Loosen the cover retaining knob and remove the

cover.

2. Remove the element cover nut, element cover, and

paper element with precleaner.

3. Remove the precleaner (if so equipped) from the

paper element.

4. Do not wash the paper element or use

pressurized air, as this will damage the element.

Replace a dirty, bent, or damaged element with a

genuine Kohler element. Handle new elements

carefully; do not use if the sealing surfaces are

bent or damaged.

5. When servicing the air cleaner, check the air

cleaner base. Make sure it is secured and not bent

or damaged. Also check the element cover for

damage or improper fit. Replace all damaged air

cleaner components.

NOTE: If any loose dirt or debris fell on the air

cleaner base when the element was

removed, carefully remove it and wipe the

base clean. Be careful that none of it

drops into the intake throat. Check the

condition of the rubber seal on the air

cleaner stud. If the condition is

questionable in any way, replace it with

the new seal packaged with the

replacement element.

6. Reinstall the paper element, precleaner, element

cover, element cover nut, and air cleaner cover.

Secure cover with the cover retaining knob.

Clean Air Intake/Cooling Areas

To ensure proper cooling, make sure the grass screen,

cooling fins, and other external surfaces of the engine

are kept clean at all times.

Every 100 hours of operation (more often under

extremely dusty, dirty conditions), remove the blower

housing and other cooling shrouds.* Clean the cooling

fins and external surfaces as necessary. Make sure the

cooling shrouds are reinstalled.

NOTE: Operating the engine with a blocked grass

screen, dirty or plugged cooling fins, and/or

cooling shrouds removed, will cause engine

damage due to overheating.

*Cleanout kits 25 755 20 (black) or 25 755 21 (gold)

allow inspection and cleanout of the cooling fins.

Ignition System

CH18-25 Engines - Use an electronic Capacitive

Discharge (CD) ignition system. Other than

periodically checking/replacing the spark plugs, no

maintenance, timing, or adjustments are necessary or

possible with this system.

CH26 Engines - Incorporate a computer controlled and

monitored ignition system with individual coils. Other

than periodically checking/replacing the spark plugs, no

maintenance, timing, or adjustments are necessary or

possible with this system.

Check Spark Plugs

Every 200 hours of operation, remove the spark plugs,

check condition, and reset the gap or replace with new

plugs as necessary. The standard spark plug is a

Champion

RC12YC (Kohler Part No. 12 132 02). A

high-performance spark plug, Champion

Gold 2071 (used on Pro Series engines, Kohler Part

No. 12 132 06) is also available. Equivalent alternate

brand plugs can also be used.

1. Before removing the spark plug, clean the area

around the base of the plug to keep dirt and debris

out of the engine.

2. Remove the plug and check its condition. Replace

the plug if worn or reuse is questionable.

NOTE: Do not clean the spark plug in a machine

using abrasive grit. Some grit could

remain in the spark plug and enter the

engine causing extensive wear and

damage.
